The video, filmed in Nigeria, showed a man trying to catch the long-horned cow with a rope on a pole, watched by a crowd.
However the cow evaded the rope and instead charged at a bystander.
As he sprinted away, the cow turned its attention to another man trying to run off.
In his desperate efforts to scramble to safety, he stumbled into a ditch and the cow stabbed him with its horns.

Robert Lange of Pictou County snaps a photo of a dolphin that washed up along the shoreline in Big Island, N.S. on Sunday, Nov. 20, 2016.
Robert Lange says he was driving home last week when he noticed a pod of dolphins splashing in the Merigomish Harbour.
"The dolphins were swimming very close to shore here and when I stopped and looked closer with the binoculars, there was a pod of maybe a dozen or more swimming very close together," said Lange. "The fins were all out of the water and the tide was very low with the supermoon."

One of the animals died that night and another washed ashore the next morning.
The dolphins appear to be trapped by geography. At one end, Merigomish Harbour has a wide opening between Big Island and the Mainland, but it narrows significantly and closes at the other end.
"We assume that these ones were probably chasing a school of fish, and got up here and got out of the channel and into the shallow water and couldn't get back," said Lange.
Snr Asst Comm Charamba said the other three boys and the teacher were treated and discharged. "With the onset of the rainy season, members of the public are urged to take precautionary measures when it is about to rain, during or after.
"Please avoid taking shelter at isolated places or being the sole target at open spaces; avoiding contact with electrical gadgets and seeking shelter under isolated tall trees or other objects," said Snr Asst Comm Charamba.
The quake struck near Fukushima at about 06:00 local time (21:00 GMT Monday), triggering initial warnings of 3m (9.8ft) high waves. The waves which eventually hit the coast were much smaller.
Thousands were asked to evacuate the area and minor injuries were reported.
An earthquake and tsunami struck the area in 2011 killing 18,000 people.
That quake, one of the most powerful ever recorded, also caused a meltdown at the Fukushima nuclear power plant, where a massive clean-up operation is still going on.
Officials have said there is no sign of damage to the plant this time.
The US Geological Survey initially put the magnitude at 7.3 but later downgraded this to 6.9, lower than the number given by the Japanese authorities.
The Japan Meteorological Agency (JMA) said in its latest update that no tsunami damage is expected, although there may be slight changes to the sea level.
The earthquake, initially estimated at magnitude 6.3, was registered at a depth of 37km (23 miles) and centered off the coast of North Island, some 123km (76 miles) from Palmerston North.
The quake struck 67km northeast of Iwaki, a city located in the southern part of the Hamadori coastal region of Fukushima Prefecture, Japan.
Comment: Update: Fukushima reactor cooling system stops following quake & tsunami
The cooling system of the third reactor at the Fukushima nuclear power plant has stopped circulating water following a powerful 7.3 offshore earthquake. TEPCO said it managed to restart the system some 90 minutes after the failure.
The cooling system servicing the Unit 3 spent fuel pool was not able to circulate water to cool the nuclear fuel because of a broken pump, according to the Nuclear Regulatory Agency.
The temperature in the pool went up to 29 degrees Celsius. It takes up to seven days for temperatures to rise to 65 degrees Celsius, which is the upper operational limit, Japan's national nuclear agency said.
At such a pace, the cooling system failure posed no "immediate danger," although the agency admitted "gradual" rise in temperatures.
The exact cause of the cooling system stoppage is currently unknown. However, the system might have been "shaken" during the earthquake, according to nuclear agency officials, as reported by NHK. The station's storage pool currently contains 2,544 spent fuel rods. No cooling water leaks or any other "abnormalities" have been reported.
The first tsunami wave which hit the nuclear power plants was about one meter high, while the second was "not very high," according to TEPCO. There has been no "major physical damage" to the nuclear power plants, NHK reported.

The flooded Whitchurch Lane in Bristol, pictured, was hit with more heavy rain during the course of the day
The Met Office issued an amber warning - the second highest severe weather alert - for Devon and parts of Somerset, predicting that up to 30mm of rain could fall within an hour. It also released a yellow "be aware" warning for areas of northern England.
By early afternoon on Monday, there were 15 flood warnings - meaning flooding is expected and immediate action is required - in Devon, Somerset and Dorset. In addition, there were 89 flood alerts (flooding is possible, be prepared) across England and Wales.
Impacts were likely to include flooding of properties and parts of communities, the Met Office said, and significant disruption to travel, with a number of roads and rail services likely to be affected.
The Environment Agency said: "Across England and Wales localised impacts from river or surface water flooding are possible. Gales and large waves will affect the east Channel coast for a time overnight, giving the potential for soma localised spray and wave overtopping here."
The man was in an elk hunting party on a creek bottom on private property near the Ear Mountain Wildlife Management Area on the Rocky Mountain Front, said Capt. Dave Holland, FWP's head game warden in Great Falls-based Region 4.
He was mauled at about 9 a.m. by a female grizzly with two cubs, he said.
"It appears the sow was protecting her cubs at this point," Holland said late Sunday afternoon.

Aibillie Elijassiapik found this one-headed, two-bodied ringed seal fetus near Inukjuak, Que., on Monday.
He assumed the seal was pregnant, and pregnant it was — but what he found in its womb was what he called, in Inuktitut, a total surprise.
He began to skin the ringed seal — a normal hunting procedure. That quickly took an unexpected turn.
"I noticed in the uterus two sets of flippers, so I was expecting to pull out two seal pups," said Elijassiapik, who said it's rare for a seal to give birth to two seal pups.
"In fact, it was only one conjoined seal pup at the head."
Elijassiapik, who has been hunting since his father taught him at a young age, said he has never seen anything like it.

Snowplows clear a main road in Mudanjiang City in northeastern Heilongjiang Province yesterday. Heavy snow fall since Friday has closed several expressways in the province.
From today until Thursday, temperatures in most of the central and eastern part of the country are expected to drop by 6 to 10 degrees Celsius, said the National Meteorological Center.
In some parts of Henan, Anhui, Hubei and Hunan provinces, the temperature will drop by up to 16 degrees, said the NMC.
Yellow is the second-most severe level on China's four-level color weather alert scheme.
The cold front will be accompanied by gales, rain and snow.
Meanwhile, under the influence of a strong cold spell, parts of Beijing have been hit by snowfall since early yesterday.
Much of the capital city has been hit with snow after 8pm yesterday.
